Application filed May 31,1913. Serial No. 771.029.

.1?) (1/! "(U/1.077! it "any conc rn Be it known that- I, Gnonon M. lltISlON, a citizen of the United States, residing at New York, in the countv M New York and t ltate at New York, have invented certain new and usel'ul lnqn-ovcmcnls in Vehicle Spring-liqualizers; and I do hereby declare the following to be a. full, clear, and exact description at the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventicn relates to vehicle springs, and has for its object to provide certain improvements in the type ol spring disclosed in Letters Patent No. 1 336,247, granted to me na gustv .20, 1912, and as disclosed in certain other Letters Patent also granted to me, the primary object of said improvement being to provide a novel term of equalizer for connecting the ends of the spring tea res with the leal spring. disclosed in said Letters Patent.

In the accoinpanyino' drawing: Figure l is a side elevation of my improved construw lion shown applied to a. vehicle axle and body, said axle being shown in section; Fig. 2 a detail sectional view on the line ll---l1 Fig. l; Fig. 3 is a similar View on the line lll---lll, Fig. l; l ig. -:-l is an enlarged detail perspective view of the spacing block or bushing employed; Fig. 5 is a detail side elevation of one men'lber oi the etpializer.

in the said drawing. the reference nil-- meral 1 denotes one of the axles of an automobile or other vehicle, the same being shown Lshaped in cross section, although it may be of any configuration. Bolted to said axle is a leat' spring 2 formed of any desired number of leaves, and projecting equidistant transversely to each side of the axle 1 though but one (it said sides is herein shown. livotally connected at 3 to the free end of said spring a rigid bar or shackle -&l-, said bar or shackle being pivoted, in a manner hereinafter described, to the two members of an equalizer. Said equalizer, as stated, is composed oil two similarly shaped members 5 disposed in parallel relation, each oil the same being provided with a single aperture 7 near one end and with a plurality of apertures 8 along its opposite end, all of said apertures registering with the similar apertures in the companion equalizer plate. Shaped to lit in either of the elongated apertures (3 is a spacing block or bushing 1) formed preferably of cast metal, and being provided with shoulders 10 agaimt which the members oi the equal izer will contact to space the same the proper distance apart, the bushing 9 projecting at 11 through the apta'lurcs ti in said equalizer members. Said bushing is bored eccentrically at 12 to receive the bolt 13 by which connection is made with the rigid bar or shackle -l-, as shown. It will be observed that when it is desired to shift the point oi connection between said shackle iand the equalizer a slight shiit't may be obtained by removing and reversing the bushing 9 to bring the bolt1-hole iii to lhe left. A still greater shift may be obtained by shifting said bushing bodily to the rcarmost elongated apertures t3, and a like minor variation in adjustment may be obtained within said apertures by reversing said lmshing, as will readily be understood.

In use, the free ends of the spring leaves 'l 'l, which are similar in construction to those disclosed in Letters Patent No. 1,036,247, hcrcinbclore referred to, arc connected to the members ot the equalizer at the points 15, while the innermost leal 1G is connected to said equalizer on the opposite side of the bar or shackle -lat it". lt will be observed that the bushing 9 by serving as a spacing member tor the members 5 of the equalizer, prevents the latter from binding upon the ends of the spring leaves 14 and 1e, leaving them tree to turn upon their connections .15 and 17. By means of the adjustment provided :lor the connection between the bar or shackle -.land the equalizer, through the bushing t) and the apertures (3, I am enabled accurately to adjust the tension of the springs 14 and '16, it being apparent that the nearer the point of connection is to the point. of connection 1.? ol spring lcal '1 (l the more flexible will be the action oil the device as a whole. By means of this adjustment l am enabled, therefore, to suit the spring to vehicles adapted to carry from two to seven persons.

llaving thus described my invention, what i claim as new and desire to secure by Letters- Patent is:

l. in combination with a plurality of similarly curved spring loaves fixed to one member in contact with each other and gradually separating toward their other ends, a leaf spring fixed to the other member, a bar or shackle pivoted to the 'tree end of said leaf spring, and an equalizer adjustably connected intermediate its length with the other end of said bar or shackle and also connected on opposite sides of the point 01 connection with said bar or shackle with the tree end of said spring leaves: 7

2, In combination with a plurality of similarly curved spring leaves fixed to one member in contact with each other and gradthe other end of said bar or shackle is pivoted, the free ends of said spring leaves being also connected to said equalizer between the spaced members thereof.

3. The combination with an equalizer having an elongated aperture therein, of a removable and reversible bolt receiving bushing shaped to fit said elongated aperture and having an eccentrically disposed bolt receiv ing bore therethrough.

' 4. The combination with an equalizer formed 01 two similarly shaped members having coinciding elongated apertures there in, of a bolt receiving bushing formed with shoulders to space apart said equalizer members' and with ends adapted to pass through said elongated aperturestherein and having 7 an eccentrically disposed bolt receiving bore therethrough.

In testimony whereof I my signature in the presence of two subscribing Witnesses.
